TH READQWAXING ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part. of Letters Patent No. 354,237, datedDecember 14, 1886.

Application filed November 21, 1885. Serial No. 163,549. (No model.)

To all whom it may concern.-

Be it known that we, WILLIAM BrennanseN and Trrnononn O. BAITER,residents of Cincinnati, in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in Thread-WaxingAttachments for Sewing-Machines, of which the following is aspecification.

This invention has for its object to provide the rotating horn of a bootand shoe sewing machine with a novel combination of devices for waxingthe thread, and this we accomplish in the manner and by the meanshereinafter described and claimed, reference being made to theaccompanying drawings, illustrating our invention, in which Figure l isa perspective view of our invention attached to the horn of asewingmachine; Fig. 2, a cross section of the waxingtank. Fig. 3 is anelevation of the side opposite to that shown in Fig. 1, showing themethod of heating the wax-tank. Fig. 4. is a sectional elevation of thewax-stripper.

A represents the shank of the ordinary horn; B, the horn proper, throughwhich the thread is passed to the wheel at the tip of the horn a.

1) represents a rack for the twine or thread ball; I), the ball; 0, thethread; G, the revolving spindle to which the horn is attached.

In operation the horn, shank, and spindle A B G are revolved oroscillated by the operator.

E represents the waXtank, which is attached either to the spindle O orto the collar 6, which secures the horn to the spindle O.

In Fig. 2 the wax-tank is shown in section. F F represent a jacketaround the reservoir G, in which the wax is melted. The space F at thebottom is filled or partly filled with water. H represents a gas-burner;h, the flame, which is consumed at the burner-tip, and impinges againstthe bottom of the reservoir and heats the water in the jacket F underthe wax-tank. I represents a partitionstrainer forming a recess, inwhich is placed a stripper, K. This partition is perforated with holes,so as to let the melted wax run through to the stripper, keeping backthe impurities.

The ball 6 is placed in the rack B. The thread is preferably passedthrough an orifice at d in the tank E, and passes under the roll 1 ofthe stripper and around rolls 2 and 3, and thence to the orifice 4 atthe base of the horn B, where it is fed to the needle in the usualmanner. Reservoir G and rack D, being rigidly at tached to the shank ofthe horn, revolve with it, and the thread is unwound and waxed as it isdrawn through by the needle operating at the tip of the revolving horn.

5 represents a burner for heating the horn.

6 represents a branch gas-pipe tapping pipe 5, and furnishing a tip forsupporting combustion under the reservoir, as shown in Fig. 3.

The stripper is readily detachable from the tank, so it can be liftedout of the melted wax to adjust the thread, and in case of breakage orstoppage to correct the same.

7 represents a rim on which the tank E sets. It is readily detachabletherefrom.

The strainer-partition in the waxing-tank extends from the bottom of thetank upward, preferably to the top thereof. The nature of the impuritiesto be kept back by the strainer are dirt, paper, lint, and other foreignsubstances which stick to waX,as well as to the ball of wax itself,which is placed in the recess back of the strainer, so that only purestrained wax is in the apartment containing the stripper.

' Any foraminous metallic disk, wire gauze, or

other material having meshes sufficiently coarse to allow the melted waxto pass through, and yet keep back the substances named, will serve thepurpose.

Having described our invention, what we claim is 1. The combination,with the upright rotating spindle G and the horn B, moving therewith, ofa wax-reservoir connected with said spindle, an upright perforatedstrainerpartition, I, extended across the reservoir, the stripper K,located in the reservoir between its wall and the perforated partition,and a heater for the reservoir, substantially as de' scribed.

2. The combination, with the rotating spindle G and the shank A, havingthe horn B and collar 6, of thewaX-reservoir rigidlyconnected with thecollar and projecting laterally therefrom, a strainer, I, extendingacross the reservoir, the stripper K, located in the reservoir and thelatter a burner beneath the wax-tank, between the Wall thereof and thestrainer, and substantially as described.

a gas-burnerlocated directly beneath the Wax- In testimony whereof wehave hereunto set reservoir, substantially as described. our hands.

5 3. The revolving horn A B and Wax-tank E, through which the thread 0passes as it is drawn through the wax and the stripper K in tank E, andthence through the hollow horn, \Vitnesses: in combination with thebranch pipes 5 and 6, ROBERT ZAHNER,
